Description

Technical Field

[0001] This invention relates to the field of anchor chain bending technology, specifically to a ship anchor chain bending forming equipment and its usage method. Background Technology

[0002] An anchor chain is a special chain that connects the anchor to the hull and transmits the anchor's holding force. It is usually composed of anchor end links, intermediate links, and end links. When used on ships, the main functions of the anchor chain are: to connect the anchor to the ship and to transmit the anchor's holding force to the hull; and when anchored, because the anchor chain has a certain weight, it can buffer the external forces such as wind and current that the ship is subjected to in the water.

[0003] The manufacturing of anchor chains under current technology is not complicated. One of the main steps is ring bending. The heated rod material is fed to the ring bending machine. A cylinder drives a cylindrical rod to bend the rod material into shape with two shaping rings on the left and right. During the process, the worker needs to change the direction of the rod material so that both ends are bent to form a closed ring.

[0004] After this bending process is completed, it is often found that the rings cannot close well, and the two ends of the rods are often misaligned. When the rings are transferred to the next welding process, they must be corrected. However, the decrease in temperature at this time will affect the correction work.

[0005] Therefore, we propose a ship anchor chain bending ring forming equipment and its usage method that can promptly align the two ends of the rod-shaped raw material after bending ring forming to avoid the temperature drop affecting the ring closure, in order to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a ship anchor chain bending and forming equipment and its usage method to solve the problems mentioned in the background art.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] An anchor chain bending and forming device includes a workbench. A chute is formed at the middle of the top of the workbench. A pusher is slidably connected inside the chute. One side of the pusher is connected to a drive cylinder. A lower column is fixedly connected to one side of the bottom of the pusher. An upper column is fixedly connected to the top of the lower column. A shaping ring is symmetrically fixedly connected to the top of the workbench on one side of the pusher. An anchor chain bar is placed on the top of the workbench on one side of the shaping ring. A straightening frame is fixedly connected to one side of the workbench. A push plate is fixedly connected to the side of the straightening frame away from the workbench via a drive cylinder. A sliding rod is symmetrically arranged on the side of the push plate near the straightening frame. A straightening ring is fixedly connected to one side of the sliding rod.

[0009] As a further aspect of the present invention: a nut is fixedly connected to one side of the top of the workbench, and a screw is connected to the internal thread of the nut.

[0010] As a further aspect of the present invention: a guide ring is symmetrically slidably connected to the side of the correction frame near the push plate, and the slide rod is slidably connected inside the guide ring.

[0011] As a further aspect of the present invention: an indicator plate is fixedly connected to the top of the guide ring, and a scale is fixedly connected to the side wall of the correction frame on one side of the indicator plate.

[0012] As a further embodiment of the present invention: a fixing plate is fixedly connected to the bottom end of the guide ring, a fixing bolt is threadedly connected to the lower end of the fixing plate, and threaded holes are evenly opened on the side wall of the correction frame on one side of the fixing bolt.

[0013] As a further aspect of the present invention: a slide rail is provided on the side of the push plate near the correction frame, and the slide rod is slidably connected inside the slide rail.

[0014] As a further aspect of the present invention: the opening diameter of the correction ring near the worktable is larger than the opening diameter of the correction ring near the correction frame.

[0015] As a further aspect of the present invention: a lifting cylinder is fixedly connected to the top of the pusher, and a sleeve plate is installed at the output end of the lifting cylinder. The diameter of the opening on the sleeve plate is equal to the diameter of the upper column, and the diameter of the lower column is greater than the diameter of the upper column.

[0016] As a further aspect of the present invention: a guide rod is fixedly connected at the middle position of the bottom end inside the pusher, and the guide rod is slidably connected on the sleeve plate.

[0017] A method for using a ship anchor chain bending and forming equipment, comprising the following steps:

[0018] S1: First, adjust the screw according to the size of the anchor chain. Rotate the screw inside the nut to adjust it to the appropriate position. Then, adjust it according to the size of the anchor chain ring. With the help of the indicator plate on the scale, adjust the guide ring and slide rod to the appropriate position and fix them by rotating the fixing bolt. Then, drive the pusher to move through the drive cylinder, so that the lower column and the upper column move towards the correction frame until the anchor chain rod can be placed between the upper column and the shaping ring. When the anchor chain rod is placed, make one end of the anchor chain rod abut against the screw, thus completing the preparation work before the anchor chain bend ring is formed.

[0019] S2: The lifting cylinder drives the sleeve plate to descend, so that the sleeve plate covers the upper column. Then, the drive cylinder drives the pusher to move, so that the anchor chain bar is bent into shape between the shaping ring and the upper column. After the bending of one side is completed, it is reset and the worker takes it out to be bent into shape on the other side.

[0020] S3: After complete bending and forming, the pusher is driven by the drive cylinder to move towards the correction frame, so that the upper column is located between the workbench and the correction frame. At this time, the ring-shaped anchor chain rests on the lower column. The worker adjusts the position of the anchor chain ring with the clamp, and then drives the push plate to move by the drive cylinder, so that the slide rod pushes the correction ring, so that the closed part of the anchor chain ring is corrected. Finally, the sleeve plate and the upper column are separated, and the bending and forming of the anchor chain is completed.

[0021] The beneficial effects of this invention are:

[0022] 1. The ship anchor chain bending ring forming equipment and its usage method in this invention use a drive cylinder to drive the push frame to move so that the upper column is located between the worktable and the correction frame. With the help of the worker, the anchor chain ring is adjusted to a suitable suspension position using a clamp. Then, the drive cylinder drives the push plate to move, so that the slide rod pushes the correction ring, thereby correcting the closed part of the anchor chain ring. This allows for correction while it is hot, avoiding the trouble of subsequent correction.

[0023] 2. The ship anchor chain bending ring forming equipment and its usage method in this invention, by replacing the corresponding correction ring and coordinating with the direction of the indicator plate on the scale, slide the guide ring and slide bar to the appropriate position, and fix them by rotating the fixing bolt, so as to ensure that the correction ring can be aligned with both sides of the anchor chain ring, thereby ensuring that it can adapt to anchor chains of different specifications.

[0024] 3. The ship anchor chain bending ring forming equipment and its usage method in this invention use a lifting cylinder to drive the sleeve plate to descend, so that the sleeve plate covers the upper column, thereby limiting the upper and lower parts of the upper column and avoiding excessive force that could cause deformation of the upper column. At the same time, the drive separates the upper column from the sleeve plate, making it easy to remove the anchor chain ring.

[0025] 4. The ship anchor chain bending ring forming equipment and its usage method in this invention adjusts the screw according to the size of the anchor chain. First, the screw is rotated inside the nut to adjust the screw to an appropriate position so that the anchor chain bar can be accurately placed and the anchor chain bar can be bent at the point of force. This ensures that the anchor chain is closed more accurately after bending, without the need for excessive manual adjustment and control of the bending point. Attached Figure Description

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1-9This embodiment of a ship anchor chain bending ring forming device includes a workbench 1. A chute 2 is provided at the middle position of the top of the workbench 1. A pusher 9 is slidably connected inside the chute 2. One side of the pusher 9 is connected to a drive cylinder. A lower column 16 is fixedly connected to one side of the bottom of the pusher 9. An upper column 17 is fixedly connected to the top of the lower column 16. A shaping ring 3 is symmetrically fixedly connected to the top of the workbench 1 on one side of the pusher 9. An anchor chain rod 13 is placed on the top of the workbench 1 on one side of the shaping ring 3. A correction frame 4 is fixedly connected to one side of the workbench 1. A push plate 5 is fixedly connected to the side of the correction frame 4 away from the workbench 1 through a drive cylinder. A slide rod 11 is symmetrically arranged on the side of the push plate 5 close to the correction frame 4. A correction ring 10 is fixedly connected to one side of the slide rod 11.

[0039] like Figures 1-3 and Figure 9 In this embodiment, a nut 14 is fixedly connected to one side of the top of the workbench 1. A screw 8 is connected to the internal thread of the nut 14. By rotating the screw 8 inside the nut 14, the screw 8 is adjusted to an appropriate position so that the anchor chain rod 13 can be accurately placed and the point of the anchor chain rod 13 under stress bend can be ensured. This ensures that the anchor chain closes more accurately after bending, without the need for excessive manual adjustment to control the bending point.

[0040] like Figures 1-6 and Figure 8 In this embodiment, the correction frame 4 is symmetrically slidably connected to the side near the push plate 5 with a guide ring 20, and the slide rod 11 is slidably connected inside the guide ring 20. The position of the slide rod 11 can be easily adjusted by sliding the guide ring 20.

[0041] like Figure 2 and Figure 8 In this embodiment, an indicator plate 19 is fixedly connected to the top of the guide ring 20, and a scale 12 is fixedly connected to the side wall of the correction frame 4 on one side of the indicator plate 19. The position of the guide ring 20 can be accurately adjusted by the indication of the indicator plate 19 on the scale plate 19.

[0042] like Figure 2 and Figure 8 In this embodiment, the bottom end of the guide ring 20 is fixedly connected to a fixing plate 21, and the lower end of the fixing plate 21 is threadedly connected to a fixing bolt 22. The side wall of the correction frame 4 on one side of the fixing bolt 22 is evenly provided with threaded holes. By rotating the fixing bolt 22, the fixing plate 21 is fixed on the correction frame 4 to achieve the fixation of the position of the guide ring 20.

[0043] like Figure 1 , Figure 3 and Figure 4 In this embodiment, the push plate 5 is provided with a slide rail 18 on the side near the correction frame 4, and the slide rod 11 is slidably connected inside the slide rail 18 to ensure the adjustment of the position of the slide rod 11.

[0044] like Figure 2 , Figure 5 and Figure 6 In this embodiment, the opening diameter of the correction ring 10 near the workbench 1 is larger than the opening diameter of the correction ring 10 near the correction frame 4, which facilitates the correction of the closed part of the anchor chain ring.

[0045] like Figures 1-3 and Figure 7 In this embodiment, the top of the pusher 9 is fixedly connected to a lifting cylinder 7. A sleeve plate 6 is installed at the output end of the lifting cylinder 7. The diameter of the opening on the sleeve plate 6 is equal to the diameter of the upper column 17, and the diameter of the lower column 16 is greater than the diameter of the upper column 17, so that the lifting cylinder 7 can drive the sleeve plate 6 to be fitted onto the upper column 17, avoiding excessive force that could cause the upper column 17 to deform or cause the sleeve plate 6 to separate from the upper column 17, thus facilitating the removal of the anchor chain ring.

[0046] like Figures 1-3 and Figure 7 In this embodiment, a guide rod 15 is fixedly connected at the middle position of the bottom of the push frame 9. The guide rod 15 is slidably connected on the sleeve plate 6 to ensure the stable up and down movement of the sleeve plate 6.

[0047] A method for using a ship anchor chain bending and forming equipment, comprising the following steps:

[0048] S1: First, adjust the screw 8 according to the size of the anchor chain. Rotate the screw 8 inside the nut 14 to adjust the screw 8 to the appropriate position. Then, adjust it according to the size of the anchor chain ring. With the guidance of the indicator plate 19 on the scale 12, adjust the guide ring 20 and slide bar 11 to the appropriate position and fix them by rotating the fixing bolt 22. Then, push the push frame 9 to move through the drive cylinder, so that the lower column 16 and the upper column 17 move towards the correction frame 4 until the anchor chain rod 13 can be placed between the upper column 17 and the shaping ring 3. When the anchor chain rod 13 is placed, one end of the anchor chain rod 13 touches the screw 8, thus completing the preparation work before the anchor chain bend ring is formed.

[0049] S2: The lifting cylinder 7 drives the sleeve plate 6 to descend, so that the sleeve plate 6 covers the upper column 17. Then, the drive cylinder drives the pusher 9 to move, so that the anchor chain rod 13 is bent and formed between the shaping ring 3 and the upper column 17. After the bending of one side is completed, it is reset and the worker takes it out to be bent and formed on the other side.

[0050] S3: After complete bending and forming, the pusher 9 is driven by the drive cylinder to move towards the correction frame 4, so that the upper column 17 is located between the workbench 1 and the correction frame 4. At this time, the ring-shaped anchor chain is placed on the lower column 16. The worker adjusts the position of the anchor chain ring with the clamp, and then drives the push plate 5 to move by the drive cylinder, so that the slide rod 11 pushes the correction ring 10, so that the closing part of the anchor chain ring is corrected. Finally, the sleeve plate 6 and the upper column 17 are separated, and the bending and forming of the anchor chain is completed.

[0051] It is understandable that the ship's anchor chain bending and forming equipment and its usage method are...

[0052] The complete usage steps and working principle of this invention are as follows:

[0053] First, prepare by adjusting the screw 8 according to the size of the anchor chain. Rotate the screw 8 inside the nut 14 to adjust it to the appropriate position so that the anchor chain rod 13 can be accurately placed and the point of force bending of the anchor chain rod 13 can be ensured. Then, adjust the guide ring 20 and slide rod 11 according to the size of the anchor chain ring. With the guidance of the indicator plate 19 on the scale 12, adjust them to the appropriate position and fix them by rotating the fixing bolt 22 to ensure that the correcting ring 10 can be aligned with both sides of the anchor chain ring. Then, push the push frame 9 by driving the cylinder to move the lower column 16 and the upper column 17 towards the correcting frame 4 until the anchor chain rod 13 can be placed between the upper column 17 and the shaping ring 3. When the anchor chain rod 13 is placed, one end of the anchor chain rod 13 touches the screw 8, thus completing the preparation work before the anchor chain bending ring is formed.

[0054] During bending, the lifting cylinder 7 drives the sleeve plate 6 to descend, so that the sleeve plate 6 covers the upper column 17, thereby limiting the upper and lower parts of the upper column 17 to avoid excessive force and deformation of the upper column 17. Then, the drive cylinder drives the pusher 9 to move, so that the anchor chain rod 13 is bent into shape between the shaping ring 3 and the upper column 17. After bending one side is completed, it is reset, and the worker takes it out to bend the other side.

[0055] After complete bending and forming, the pusher 9 is driven by the drive cylinder to move towards the correction frame 4, so that the upper column 17 is located between the workbench 1 and the correction frame 4. At this time, the ring-shaped anchor chain rests on the lower column 16. The worker adjusts the position of the anchor chain ring with the clamp, and then drives the push plate 5 to move by the drive cylinder, so that the slide rod 11 pushes the correction ring 10, so that the closed part of the anchor chain ring is corrected. Finally, the sleeve plate 6 and the upper column 17 are separated, and the bending and forming of the anchor chain is completed.
